Hello I Am A 16 Years Old Guy, And Had

Hello I am a 16 years old guy, and had gotten chlamidia about 3 weeks ago and I finally built up the nerve to tell my parents and the took me to the doctor and I got cured. Well anyways last week I got with a girl and foolishly had unprotected sex, and later I learned she had chlamidia.. So I told my mom I need to go back to the doctor for more antibiotics. Can I tell the doctor what really happened without him telling my mom?
